(Sharecast News) - Credit checker Experian was top of the FTSE 100 gainers board on Thursday afternoon gained after the company said full-year profits fell but revenue growth accelerated towards the end of the year,National Grid followed close behind after reporting a 4% rise in full-underlying pre-tax profit.

On the corporate front, gambling stocks recovered from earlier losses as the government confirmed that the maximum stake on fixed-odds betting terminals (FOBTs) will be further reduced from £50 to £2. Paddy Power Betfair, GVC Holdings and 888 Holdings all reversed course to trade higher.

George Salmon, equity analyst at Hargreaves Lansdown, said: "The change will impact profits at the big high street bookmakers, but the US Supreme Court's decision to open up the sports betting market over the pond means shares in the sector are still likely to end the week higher."

"The potential in the US is enormous. Around $150bn is already wagered on the underground market every year, and this will surely rise as barriers to betting are removed. For the UK bookies, the chance to tap into this huge potential could mean lost machine revenues are more than replaced. What's likely to follow is something of a land grab. First out of the blocks is Paddy Power Betfair, which is already in discussions about a new US partnership."
